More about gelling and how to use

Diesel Winter Anti-Gel provides “Premium Diesel” qualities to standard diesel fuels in terms of detergency, stability, lubricity, winter operability, and cetane number. Diesel fuel contains wax, as temperatures drop these wax crystals clog fuel lines and cause problems for diesel engines. Our effective anti-gel additive greatly improves cold temperature performance and helps prevent the wax in the fuel from clogging lines. Additional properties provide further winter protection against freeze-ups. In addition, Diesel Winter Anti-Gel contains a powerful cetane improver for quicker cold starts and a maximum boost in power and performance. Diesel Winter Anti-Gel is recommended for ALL diesel engines.

Diesel Winter Anti-Gel should be used in every fill-up during the cold winter months. Recommended treatment rates are 1:1000 for #2 diesel.

The sulfur content of this diesel fuel additive does not exceed 15 ppm. This diesel fuel additive complies with the federal low sulfur content requirements for use in diesel motor vehicles and nonroad engines.

Frequently Asked Questions About Diesel Winter Anti-Gel

You count on your diesel anti-gel additive to keep your engine running in cold weather conditions, so you want to choose a product you feel confident will perform to your expectations. To make an informed purchasing decision, review the answers to some common questions about Diesel Winter Anti-Gel. You can also reach out to our team online for additional information.

How does Hot Shot’s Secret Diesel Winter Anti-Gel work?

Diesel Winter Anti-Gel works to improve winter operability using three different chemicals — a wax modifier, a wax anti-settling agent and a military-grade de-icer. The wax modifier significantly reduces the point at which wax in diesel fuel solidifies, and the wax anti-settling agent keeps the wax dispersed once the precipitation temperature is reached. Finally, the de-icer disperses moisture, preventing it from clogging and freezing fuel filters in temperatures as low as -40 °F.

The recommended treatment ratio for Hot Shot’s Secret Diesel Winter Anti-Gel with #2 diesel is 1:1,000. Therefore, use approximately 1 ounce of anti-gel for every 8 gallons of fuel for the best results.

Will Diesel Winter Anti-Gel work with my engine?

Our anti-gel formula is safe for use in all diesel engines, including marine, semitruck, construction, agriculture, RV and racing engines. Just a few popular engines Diesel Winter Anti-Gel effectively treats includes models from Cummins and Saab, GM’s Duramax and the Ford Power Stroke.

When should I add Diesel Winter Anti-Gel?

Diesel Winter Anti-Gel is the ideal fuel additive to use in cold weather when you want to improve cold starts, prevent gelling and icing, reduce fuel line freeze, boost cetane and improve fuel economy. Add one treatment of Diesel Winter Anti-Gel with every fill-up for consistent protection against low-temperature performance issues.

Please note that Diesel Winter Anti-Gel is intended for everyday cold weather use. For emergency situations in which fuel or fuel filters have already frozen, use Hot Shot’s Secret Diesel Winter Rescue.

Can I use Diesel Winter Anti-Gel with Everyday Diesel Treatment (EDT)?

Diesel Winter Anti-Gel provides all the same protections and benefits of Everyday Diesel Treatment -EDT with the addition of an anti-gel. All you need to use is Diesel Winter Anti-Gel.

Can I use Diesel Winter Anti-Gel with biodiesel?

We do not recommend using Diesel Winter Anti-Gel with diesel blends containing more than 20% biodiesel.

How should I store Diesel Winter Anti-Gel?

Once mixed with diesel, our anti-gel additive protects fuel to temperatures as low as -65° F. However, the freezing point of Diesel Winter Anti-Gel is higher before it is added to diesel. We recommend storing the product at a minimum temperature of 20°F for this reason. You should also take care to keep the product away from sources of ignition and always reseal the container tightly to prevent leaks. For more detailed storage and use information, see the official safety data sheet.

Will using Diesel Winter Anti-Gel void my engine’s warranty?

No, using Diesel Winter Anti-Gel will not cause damage to your engine or void your manufacturer’s warranty. That’s a guarantee.
